Answer:
271cm^2
Explanation:
volume 1= 15^3 =3375
temp. 1. = 20+273 = 293
temp. 2. = 50+273 = 353
volume 2 =?
According to Charles law
volume is proportional to temperature
v2 = v1 * t2 / t1
v2 = 3375 * 353 / 293
v2 = 4066cm^3
v = area * length
4066 = area * 15
area = 4066/15 = 271cm^2
I think Option B, i’m sorry if that’s wrong.
All of the light bulbs in the series circuit would go out.

Answer:
The time at maximum height is 2.49 s.
Explanation:
The time (t) at the maximum height can be found using the following equation:
Where:
: is the final velocity = 0 (at the maximum height)
: is the initial velocity = 80 ft/s
g: is the gravity = 9.81 m/s²
Hence, the time is:
Therefore, the time at maximum height is 2.49 s.
I hope it helps you!
